+EARTH DAY BADGE
-'''Global warming''' is a term generally used to describe an increase in the global average surface (air at surface) temperature.
-As far back as temperature records can be reconstructed, periods of global warming and global cooling have alternated; see [[ice age]]s and [[interglacial warming]].
-The term is most often used to refer to the  modern period of global warming, an increase of {{temperature|0.8|1.4}} has been measured at weather stations throughout the world, since around 1850, when instrumental measurements began to be taken and organized records began to be kept. Although only a small increase in absolute terms, the temperature increase is unprecedented within at least the last 14,000 years according to the reconstructions by Viau et al. (2006) <ref>http://www.citeulike.org/user/kmcolo/article/618203 Viau et al. (2006) 'Millennial-scale temperature variations in North America during the Holocene' in Journal of Geophysical Research, 111</ref> and can have a significant impact upon the earth. Since this happens to correlate with increases in [[carbon dioxide]], many have speculated about their possible relationship.  Despite this, there is no completely proven model explaining the rise in global temperatures.

+I give the Earth a hand.
-Although measurements have been made of the temperatures of other planets these are by no means thorough or comparable with the measurements used for earth. The short space of time over which measurements have been taken and the very limited spatial coverage means that reliable average figures have not been obtained. They have certainly not been taken extensively enough to produce a five year average temperature, which is the standard when determining temperature trends on earth.

-==Controversy==
+I'm an Earth Day helper
+Each and every day.
-{{main|Global Warming Controversy}}
+I take care of Mother Earth
+In oh, so many ways.
-Since 1989, advocates have clashed on the issue of whether human beings are more responsible than nature for  modern periods of global warming; see "[[greenhouse warming]]" and [[global warming theory]].<ref>Some people predicted "global warming," which has come to mean extreme [[greenhouse warming]] of the atmosphere leading to catastrophic environmental consequences. [http://www.junkscience.com/news/robinson.htm]</ref>
-Most non-scientific support for the global warming theory rests on popular accounts such as Al Gore's ''[[An Inconvenient Truth]]'' or on reports issued by the UN's [[IPCC]]. However, Keston Green of Monash University and Scott Armstrong of the Wharton School wrote that:
-*Because the forecasting processes examined in Chapter 8 overlook scientific evidence on forecasting, the [[IPCC]] forecasts of climate change are not scientific. <ref>http://www.forecastingprinciples.com/Public_Policy/WarmAudit31.pdf</ref>
-Former vice-president [[Al Gore]] calls it a [[moral issue]], while climate scientist [[Richard Lindzen]] says, "It is probably the most immoral thing you could do to restrain energy so that the billions in the earth who don’t have access to electricity won't conveniently get it." <ref>http://www.americaabroadmedia.org/media/On line extra materials/Climate change - lindzen interview.doc</ref>
-However, it is to be noted that many proponents of the theory propose energy conservation only until 'green' energy generation becomes predominant.
-In the general, the term ''global warming'' can be used for any upward trend in the [[Global mean temperature record|global mean temperature]], but it is mostly used to refer to the 1° F warming since 1850.
-The two sides are divided on whether this warming is a natural recovery from the [[Little Ice Age]] or a man-made environmental phenomenon. There are also debates regarding the potential positive or negative effects of a warming.
-Republicans and Democrats in the U.S. are evenly split on the issue. ''Boston Globe'' writer [[Ellen Goodman]] wrote:
-* Only 23 percent of college-educated Republicans believe the warming is due to humans, while 75 percent of college-educated Democrats believe it. <ref> [http://www.boston.com/news/globe/editorial_opinion/oped/articles/2007/02/09/no_change_in_political_climate/] </ref>
-Controversy and scientific inaccuracies may have contributed to addressing 'Climate Change' in place of using Global Warming. As the northern pole region melts, the southern pole region ice is growing <ref>[http://www.csmonitor.com/2008/0110/p14s01-sten.html], http://www.csmonitor.com/2008/0110/p14s01-sten.html, As arctic ice melts, South Pole ice grows, January 10, 2008</ref> <ref>[http://www.news.com.au/story/0,27574,25348657-401,00.html Antarctic ice is growing, not melting away] News.com.au, April 18, 2009</ref> The conclusion is that for alarmists to claim a global threat, it would have to include the entire globe. The evidence is conclusive, there is no threat.
-==The Modern Warm Period==
-The Average [[Earth]] surface air temperature has risen about 1° F since 1970.
-<ref>Hansen's group at the Goddard Institute wrote, "Global warming is now 0.6&nbsp;°C [1.0&nbsp;°F] in the past three decades and 0.8&nbsp;°C [1.4&nbsp;°F] in the past century." http://data.giss.nasa.gov/gistemp/2005/</ref> Studies have ruled out the possibility that errors in the measurements and sampling significantly affect the temperature trends detected over the past century. This accounts for spatial errors in the sampling and thus also incorporates errors associated with the urban-heating effect. According to Karl et al. (1993) ''"Results imply that the errors associated with century-scale trends of temperature are probably an order of magnitude smaller than the observed global warming of nearly 0.5°C per 100 years since the late nineteenth century"'' <ref>http://adsabs.harvard.edu/abs/1994JCli....7.1144K Karl et al. (1993) 'Global and Hemispheric Temperature Trends: Uncertainties Related to Inadequate Spatial Sampling' in Journal of Climate, 7(7); 1144 - 1168</ref>
-According to temperature reconstruction made within an [[Old Earth]] paradigm, there have been many cycles of naturally-caused global warming and cooling over many millions of years (see [[climate cycles]]). Some scientists, including [[Richard Lindzen]] of [[MIT]], [[Sallie Baliunas]] of [[Harvard]] and [[Fred Singer]] (independent), say that the recent warming could be part of another natural cycle or random fluctuations in the atmosphere. However, many scientists also think that human activities were most likely the cause of the the planet's recent warming.
-== Sun Spots ==
-Sunspot activity may be a primary factor in climate fluctuations, according to Willie Soon, a researcher affiliated with the Harvard-Smithsonian Center for Astrophysics and the Harvard College Observatory. '''“The sun is a great driving force to climate change.”''' Soon said that there have been much greater temperature fluctuations due to sunspots in the past and that proponents of global warming need to consider the effects of sunspot activity on global temperatures. Brian Farrell, a Harvard meteorology professor,  acknowledged a connection between sunspot activity and temperatures on the Earth, “A strong correlation between the amount of radioactive carbon and temperature from ice cores has shown that solar activity can affect temperature." <ref>[http://www.tgdaily.com/content/view/42006/181/ Harvard astrophysicist: Sunspot activity correlates to global climate change] TGDaily.com, April 10, 2009</ref>
-==Liberal claims of "Consensus"==
-[[Richard Lindzen]] wrote in 1992,
-:Indeed, a recent Gallup poll of climate scientists in the American Meteorological Society and in the American Geophysical Union shows that a vast majority doubts that there has been any identifiable man-caused warming to date (49 percent asserted no, 33 percent did not know, 18 percent thought some has occurred; however, among those actively involved in research and publishing frequently in peer-reviewed research journals, none believes that any man-caused global warming has been identified so far). <ref name="cato">http://www.cato.org/pubs/regulation/regv15n2/reg15n2g.html</ref>
-Oddly enough, even though 82% of US climate scientists refused to support the global warming theory then, [[liberal]] activists were already claiming a scientific consensus for [[anthropogenic global warming]]. (It's hard to understand how 18 percent credence in ''any'' global warming translates into "consensus" support for ''human-caused'' global warming.)
-The campaign to convince the public (and their elected representatives) that the "science is settled" began in 1988 or 1989.
-By the 2008 elections both candidates for the Presidency of the United States were proposing plans to mitigate climate change.
-Over 31,000 American scientists have signed the petition rejecting global warming. <ref>[http://www.petitionproject.org/</ref>
-[[Image:Teller_Card_100dpi.jpg|600px|center|thumb| Global Warming Petition]]
-It is well understood that most media companies do not offer balanced reporting. Many politicians have bought into the liberal claim of consensus, for example Barack Obama's views, "Few challenges facing America and the world are more urgent than fighting climate change. The science is beyond dispute and the facts are clear." <ref>[http://cato.org/special/climatechange/ Climate Change Reality] Cato Institute</ref> In fact, many scientists disagree with the "facts," their certainty, and their interpretation. Over 100 of them have signed the statement that appears in the Cato Institute's newspaper ad. Liberals have failed to back up their claims with any scientific facts.
-[[File:ad.jpg|center]]
-==Natural Variability of the Climate System==
-It is virtually universally accepted amongst climatologists that the earth has experienced numerous [[Ice Age|ice age]]s over two million years, during which global temperatures fluctuated created glacial and inter-glacial periods. The frigid temperatures allowed ice sheets to expand southward, covering much of [[Asia]], [[Europe]], and [[North America]]. The cooling associated with ice ages is gradual, while the terminations are relatively rapid. However, even the rapid terminations of ice ages take centuries to millennia.
-==Natural Climate Change on Other Planets==
-Since the [[Viking spacecraft]] reached [[Mars]] in the 1970s until recent readings were taken, the average temperature on Mars has risen {{temperature|0.6|1.1}} just as the average temperature on the earth has risen.  Since human industrialization is clearly not to blame for the change on Mars, other causes are being considered.  One possibility is that dust storms are changing the albedo of the planet, allowing it to warm, while another possibility is that solar variations from the sun are causing the warming.<ref>http://www.space.com/scienceastronomy/070404_gw_mars.html</ref><ref>http://www.heartland.org/Article.cfm?artId=17977</ref>
-Recently, it has also been found that similar to the Earth and Mars, [[Neptune]] is also undergoing global warming.  Measurements taken at the Lowell observatory in [[Arizona]] have shown an increase in Neptune's brightness and temperature since 1980 following the same pattern seen on Earth and Mars.  The researchers who discovered this warming suggest there may be a correlation between the warming and solar variations.<ref>http://www.agu.org/pubs/crossref/2007.../2006GL028764.shtml</ref>
-[[Pluto]] has also been found to be undergoing global warming.  The overall temperature increase on Pluto has been greater than that on the earth.<ref>http://www.space.com/scienceastronomy/pluto_warming_021009.html</ref>
-On the other hand [[Uranus]] has had no net change in temperature since 1977.  A rapid increase in temperature reversed itself.  The reasons for this are not understood.<ref>http://www.boulder.swri.edu/~layoung/eprint/ur149/Young2001Uranus.pdf</ref>
-Global temperatures change on other planets even when there is no life, something which strongly supports the idea that humans are not necessarily the cause of earth's global warming.  Moreover, the temperature on Uranus has fluctuated back and forth.  There is no reason that fluctuations cannot occur on earth, too.
-Although measurements have been made of the temperatures of other planets these are by no means thorough or comparable with the measurements used for earth. The short space of time over which measurements have been taken and the very limited spatial coverage means that reliable average figures have not been obtained. They have certainly not been taken extensively enough to produce a five year average temperature, which is the standard when determining temperature trends on earth.
-However, if accurate measurements could be made, and their accuracy and reliability is improving over time, then they may prove useful to climate science. Their different atmospheres and distances from the sun provide natural laboratories to study climatic changes without human influences. Though of course they will not be directly comparable due to the vast differences.
-==Politics of Global Warming==
-{{main|Politics of global warming}}
-Christine Stewart- Canadian Environment Ministry, "'''No matter if the science is all phony''', there are collateral environmental benefits . . . Climate change provides the greatest chance to bring about justice and equality in the world.” <ref>[http://www.aim.org/wls/use-environmentalism-to-change-the-world/ Christine Stewart] Accuracy in Media</ref>
-'Global Warming Now World's Most Boring Topic’ <ref>http://newsbusters.org/node/14167</ref>
-The need to fight "global warming" has become part of the dogma of the liberal conscience. <ref name="cato" />
-Clearly, "global warming" is a tempting issue for many very important groups to exploit.
-... dealing with the threat of warming fits in with a great variety of preexisting agendas [like] dissatisfaction with industrial society (neopastoralism), ... governmental desires for enhanced revenues (carbon taxes), and bureaucratic desires for enhanced power. <ref name="cato" />
-If their biased findings are to be believed, the IPCC concluded that the global average surface temperature warmed about 0.6&nbsp;°F during the 20th Century. <ref>[http://www.answers.com/topic/global-warming Growing Signals of Global Warming] U.S. History Encyclopedia</ref> The IPCC is desperate to claim the 20th century-- the warmest on record. Thus, tying the progress of modern mankind to our supposed planet imbalance problem. Unfortunately for the IPCC, that point is disputed as well. In 2008, it was discovered that tree rings in Finland were more accurate record of the warmest century. The current era was not the warmest period-- it was the period between 931 and 1180. <ref>[http://tbirdnow.mee.nu/archive/2008/6?page=2 The Trees of Finland; Temperature Readings and Historical Reconstruction] Tbirdnow.mee.nu Blog (with links to actual data sources), June 24, 2008</ref>
-Assessments of climate science by the [[United Nations]] (see [[IPCC]] - ''Intergovernmental Panel on Climate Change'')
-have claimed that scientists are 90% sure that over 50% of the observed global warming in recent decades is human-caused, and that continued global warming should be expected over at least the next century.
-Several prominent scientists have pointed out the [[politicized science]] of the UN's assessment methods. The scientific reports are submitted to a panel of representatives appointed by each country in the IPCC. Several scientists whose research demonstrates that climate change is taking place have complained about their work being misrepresented by the U.N.
-In addition, a number of the participants have testified to the pressures placed on them to emphasize results supportive of the current scenario and to suppress other results. That pressure has frequently been effective, and a survey of participants reveals substantial disagreement with the final report. <ref name="cato" />
-Richard Lindzen wrote:
-:Perhaps more important are the pressures being brought to bear on scientists to get the "right" results. Such pressures are inevitable, given how far out on a limb much of the scientific community has gone. The situation is compounded by the fact that some of the strongest proponents of "global warming" in Congress are also among the major supporters of science (Sen. Gore is notable among those). <ref name="cato" />
-Christopher Monckton wrote an article titled Climate Sensitivity Reconsidered.
-:States that Intergovernmental Panel on Climate Change studies are flawed. The present analysis suggests the models failure to predict other climatic phenomena arises from defects in its evaluation of radioactive forcing, no-feedbacks climate sensitivity parameter and feedback multiplier. In conclusion, that there may be no "Climate Crisis" and for governments to reduce emissions may be pointless or even harmful. <ref>http://www.aps.org/units/fps/newsletters/200807/monckton.cfm , Climate Sensitivity Reconsidered, July 2008</ref> This was published on a forum of the American Physical Society with the following disclaimer "The article has not undergone any scientific peer review" and "the APS disagrees with the articles conclusions" In fact, the APS disagrees with the article without ever reviewing it.
-Ryan N. Maue:
-:A doctoral student at the Department of Meteorology at Florida State University did a study of global tropical cyclone activity. It's conclusions state that  global warming might be greatly overblown. <ref>[http://www.pittsburghlive.com/x/pittsburghtrib/opinion/s_617111.html# Global warming? More doubts] Pittsburgh Tribune, March 21, 2009</ref> Mr. Maue found that tropical cyclone activity worldwide "has completely and utterly collapsed" during the past two to three years with energy levels sinking to those of the late 1970s.
-Dr. Vincent Gray:
-:A member of the IPCC’s expert reviewers’ panel asserts, “There is no relationship between warming and the level of gases in the atmosphere,” and "there is no serious threat to the climate" <ref>[http://americanfreedomnow.com/2009/06/04/the-panic-over-global-warming-is-totally-unjustified-says-vice-chair-ipcc/ “THE PANIC OVER GLOBAL WARMING IS TOTALLY UNJUSTIFIED” says Vice Chair, IPCC] Americanfreedomnow.com, June 4th, 2009</ref>
-Joe D’Aleo: Climatologist

-Dr. John S. Theon:
-:Retired senior NASA atmospheric [[scientist]], Dr. John S. Theon, the former boss of global warming alarmist James Hansen of [[NASA]], rebukes him declaring “climate models are useless.” “My own belief concerning anthropogenic climate change is that the models do not realistically simulate the climate system because there are many very important sub-grid scale processes that the models either replicate poorly or completely omit,” “Furthermore, some scientists have manipulated the observed data to justify their model results." <ref>[http://newsbusters.org/blogs/tom-blumer/2009/01/28/former-boss-rebukes-nasa-global-warming-alarmist-hansen-agw-skeptic Former Boss Rebukes NASA Global Warming Alarmist Hansen, Is AGW Skeptic] NewsBusters.org, January 28, 2009 </ref>
-Sammy Wilson -Ireland's environment minister

-*“Everywhere you are told that man-made [[climate change]] is proved beyond doubt,”  “But you are being told lies.”
-*“This is a story of how a theory about climate turned into a political [[ideology]] ... it is the story of the distortion of a whole area of [[science]].”
-*“as the frenzy over man-made [[global warming]] grows shriller, many senior scientists say the actual scientific basis for the [[theory]] is crumbling.”
-Geology professor and scientist at the University of Oklahoma, [[David Deming]] talks about a biased [[AP]] article mentioning global warming "...whether it's continuing that was completely beyond the evidence." <ref>[http://www.foxnews.com/story/0,2933,468084,00.html Scientists Call AP Report on Global Warming 'Hysteria'] Fox News, December 16, 2008</ref>
-     The mean global temperature, at least as measured by is now the  same as it was in the year 1980.
-     In the last couple of years sea level has stopped rising.
-     Sea ice globally is also the same as it was in 1980.
-     Hurricane and cyclone activity in the northern hemisphere is at a 24-year low.
-Also in discussion of the biased AP report, Michael R. Fox, a retired nuclear scientist and chemistry professor from the University of Idaho says, "There is little evidence to believe that man-made carbon dioxide is causing temperature fluctuation. Other factors, including sun spots, solar winds, variations in the solar magnetic field and solar irradiation, could all be affecting temperature changes."
-Richard S. Courtney, a U.N. Intergovernmental Panel on Climate Change (IPCC) expert reviewer and a U.K.-based climate and atmospheric science consultant says  "Rubbish! Global warming is not 'accelerating," and "...that anybody who proclaims that 'Global warming is accelerating' is a liar, a fool, or both." <ref>[http://www.newsmax.com/brennan/global_warming_debunked/2008/12/16/162489.html Global Warming’s Last Gasp] NewsMax, December 17, 2008</ref>
-Don J. Easterbrook, Ph.D., emeritus professor of geology at Western Washington University, asked, "What does it take to ignore 10 years of global cooling....? The answer is really quite simple — just follow the money!"
-==Al Gore's Claims==
-*[[Al Gore]] claims that Himalayan glaciers are shrinking and global warming is to blame. Yet the September 2006 issue of the American Meteorological Society's Journal of Climate reported, "Glaciers are growing in the Himalayan Mountains, confounding global warming alarmists who recently claimed the glaciers were shrinking and that global warming was to blame." <ref name="sun">http://www.suntimes.com/news/otherviews/450392,CST-EDT-REF30b.article</ref>
-*Gore claims the snow cap atop Africa's Mt. Kilimanjaro is shrinking and that global warming is to blame. Yet according to the November 23, 2003, issue of Nature magazine, "Although it's tempting to blame the ice loss on global warming, researchers think that deforestation of the mountain's foothills is the more likely culprit. Without the forests' humidity, previously moisture-laden winds blew dry. No longer replenished with water, the ice is evaporating in the strong equatorial sunshine." <ref name="sun" />
-*Al Gore is therefore an example of how in such an important debate, [[deceit]]ful tactics have been used by liberals to make a position seem more solid than it is.
-==2008 Presidential candidates on climate Change==
-[[Bob Barr]] is the only major 2008 Presidential Candidate who has not adopted wholesale the theory of human-caused global warming.
-According to his website,<ref>[http://www.johnmccain.com/Informing/News/PressReleases/BA6709C3-B27D-4EF9-81E6-2BA9D6F8AB20.htm John McCain on Global warming.]</ref> [[Republican]] Presidential candidate [[John McCain]] will take a more "aggressive approach" to global warming which he has declared as "undeniable and urgent." He was supported in this in June 2008 by Republican governor [[Arnold Schwarzenegger]] who said McCain was the "real deal on the environment".<ref>[http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2008/06/30/MNDB11H66C.DTL&type=politics Schwarzenegger backs McCain on climate Change]</ref>.
-In his own words, McCain says "the overwhelming majority of scientific opinion in America today, and in the world, is that climate change is real. The fact is that it ''is'' real. The fact is that the solution to it is the development of technologies.... and a [[cap and trade]] proposal.... the debate is over."[http://www.youtube.com/watch?v=gQMxIwpK_es] Unless McCain believes that Global Warming is entirely or largely man-made, there would be no sense in supporting a cap and trade solution.
-[[Barack Obama]] believes "that global warming is not just the greatest [[environmental]] [[challenge]] facing our planet—it is one of our greatest challenges of any kind." During his first 100 days in office, he would enact a giant and far-reaching [[tax]] "an economy-wide cap on U.S. carbon emissions that will reduce U.S. emissions by the amount scientists agree is necessary (80% by 2050). With worldwide cuts in emissions estimated to cost '''$45 Trillion dollars''' overall. <ref>[http://business.timesonline.co.uk/tol/business/industry_sectors/natural_resources/article4079036.ece World needs $45 trillion energy revolution] Timesonline.uk, June 6, 2008</ref> He comments "Putting a price on carbon is the most important step we can to take to reduce emissions."<ref>[http://presidentialprofiles2008.org/Obama/tab1.html League of Conservation Voters] presidentialprofiles2008.org</ref>
-==Al Gore's "Inconvenient Truth" Movie Claims==
-A [[British]] court has determined that Al Gore's movie "An Inconvenient Truth" contains at least eleven material falsehoods <ref>[http://newsbusters.org/blogs/noel-sheppard/2007/10/09/court-identifies-eleven-inaccuracies-al-gore-s-inconvenient-truth], http://newsbusters.org/blogs/noel-sheppard/2007/10/09/court-identifies-eleven-inaccuracies-al-gore-s-inconvenient-truth, October 9, 2007</ref>
-Those inaccuracies include the following
-* The film claims that melting snows on Mount Kilimanjaro evidence global warming. The Government's expert was forced to concede that this is not correct.
-* The film suggests that evidence from ice cores proves that rising CO2 causes temperature increases over 650,000 years. The Court found the film misleading: over that period the rises in CO2 lagged behind the temperature rises by 800-2000 years.
-* The film uses emotive images of [[Hurricane Katrina]] and suggests that this has been caused by global warming. The Government's expert had to accept that it was "not possible" to attribute one-off events to global warming.
-* The film shows the drying up of Lake Chad and claims that this was caused by global warming. The Government's expert had to accept that this was not the case.
-* The film claims that a study showed that polar bears had drowned due to disappearing arctic ice. It turned out that Mr Gore had misread the study: in fact four polar bears drowned and this was because of a particularly violent storm.
-* The film threatens that global warming could stop the Gulf Stream throwing Europe into an ice age: the Claimant's evidence was that this was a [[scientific]] impossibility.
-* The film blames global warming for species losses including coral reef bleaching. The Government could not find any evidence to support this claim.
-* The film suggests that the [[Greenland]] ice covering could melt causing sea levels to rise dangerously. The evidence is that Greenland will not melt for millennia.
-* The film suggests that the Antarctic [[ice]] covering is melting, the evidence was that it is in fact increasing.
-* The film suggests that sea levels could rise by 7m causing the displacement of millions of people. The evidence is that sea levels are expected to rise by about 40cm over the next hundred years and that there is no such threat of massive migration.
-* The film claims that rising sea levels has caused the evacuation of certain Pacific islands to [[New Zealand]]. The Government are unable to substantiate this and the Court observed that this appears to be a false claim.
